Application filed August 13, 1919. Serial No. 317,199.

To all whom it may concern:

Be it known that I, GEORGE H. BUGEN- HAGEN, a citizen of the United States, and a resident of the city of Minot, in the county of lVard and State of North Dakota, have invented a new and useful Improvement in of which the following is a full, clear, and exact description.

My invention relates to improvements in and it consists in the combinations', constructions and arrangements herewith described and claimed.

An object of my invention is to provide is simple in construction, easily operated, and is not liable to get out of order.

A further object of my invention is to provide a lawn swing which is rigidly supported, and which is provided w1th seats for one or more occupants, each of wh1ch may assist in propelling the swing.

A further object of my invention is to. provide a device -of the type described in which the propulsion of the swing may be effected by means of. the hands and feet.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularl pointed out in the appended claims.

y inventionis illustrated in the accompanying. drawing, which is a perspective view of the swing.

In carrying out my four supportin together at tening invention, I provide posts 1, wh1ch are o1ned their tops by any suitable fassuspension bars 3 and 4 respectively, these bars being braced at their ends by inclined braces 5 and 6. Horizontally placed bars "7 and 8 are also provided, as clearly shown in the drawing. The bars 3 and 4, together with the bars 5, 6, 7 and 8 form a supportin frame.

he carrier is formed by two parallel side pieces 9 and 10, bearin seats 11, which may be arranged in tan em or facing one another, as shown. The carrier thus formed is pivotally suspended at its ends by means of suspension bars 12 and 13 from the ends of the bars 3 and 4. Strengthening braces 14 are provided near the upper ends of the suspension bars 12 and 13. Pivot rods 15 are provided for spacing the ends of. the frame bars 3 and 4, and for pivoting the suspension bars 12 and 13 thereto.

the other. direction.

.and pulling, the swing acquires means 2. Extending transversely with respect to the posts are two parallelv One set of sus ension bars is extended below the pivota connection 16 with the carrier frame? To the ends of these extended suspension bars is pivotally connected a pair of propulsion bars 17 and 18. The latter have connected withthem at one or more points levers 19 which are pivoted at 20 to the carrier frame, and which have pivotal connections to the bars 17 and 18, as shown. These levers are formed by separate pieces which are connected to the carrier frame. At the upper end of the levers are the cross rods 21, which form operating handles, while at the lower ends are cross rods 22 which form foot rests. 1

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. The operator 23 seated in the carrier with his hands on the bar 21 and his feet on the bar 22, pulls the handle 21 toward him and his feet. This tends to apply pushes with a force to the suspension bars 12 and 13 to swing them outwardly. At the end of the outward movement, t e operator pushes on the bar 21, tending to propel the swing in By alternately pushing a greater movement.

The power ratio may be changed to any desired ratio by simply having a series of holes in the suspension member, so that the large or short lever arm is obtained below i the carrier, thus making the power adaptable to one operator or to any number of opera: tors.

form of the-invention, it is obvious that the same principle might apply to many diflz'erent forms and sizes without departing from the spirit of the invention. j

While I have described I one particular I portions to the said supporting posts near the upper ends of the latter, a second pair of parallel supporting bars arranged to lie in a lower horizontal plane than the'first named parallel supporting bars and having their ends secured to said supportingposts, and mclined bracing barscon'necting the ends of said first named supporting bars and said second named supporting bars, a carrier, suspension bars pivotally secured to said carrier and having their u per ends pivotally connected to the ends 0 said first named parallel supporting bars, certain of said suspension bars being extended below the carrler, a lever fulcrumed on said carrier, said lever comprising spaced bars having connecting rods at each end, one of said connecting rods serving as a hand bar and the other as a foot rest, and rigid connecting links extending from the lower end of said lever to said suspension bars.

2. A lawn swing-having rigid inclined supporting posts connected together at a common point at their tops, a supporting frame carried by said posts, said frame comprising a pair of parallel supporting bars arranged to lie in the same horizontal plane and being connected adjacent their middle portions to the said supporting posts near the upper ends of the ladder, a second to the lower end pair of parallel sup orting bars arranged to lie in a lower horizontal plane than the first named parallel supporting bars and having their ing posts, and inclined bracing bars connecting the adjacent ends of said first named supporting bars and said second named supporting bars, a rectangular carrier, suspension bars pivotally secured to said carrier and having their upper ends pivotally connected to the ends of said first named parallel supporting bars, certain of said suspension bars being extended below the carrier, a lever fulcruined on said carrier, said leve1"comprising spaced bars having connecting rods at each end, one of said connecting rods serving as a hand bar and the other as a foot rest, and rigid connecting links connecting the lower end of said lever of the extended suspension bars.
